6. IISEE-net http://iisee.kenken.go.jp/net/index.htm Internet-based system designed to disseminate a variety of technical information regarding seismology and earthquake engineering. Free Web site to find technical information about seismic networks, the strong motion observatory network, seismic damage archives, seismic design codes, and microzonation data of developing countries. Technical information on IISEE-net was obtained mainly through the International Training Program on Seismology and Earthquake Engineering and its ex-participants. IISEE-net works not only as a system to disseminate technical information, but also as an forum for interactive information exchange among research institutes and researchers in developing countries.
